Post A/C Trouble - 2001 C320 - Unit shuts on and off

I have recently purchased a 2001 C320. The A/C unit has not worked since the purchase. It only comes on for about 1 second and then quickly shuts down. The control unit looks like it's still functioning, but there is nothing coming out. No air flow whatsoever. It will turn on intermittently a few times during a drive, but quick shut off (after only 1 second). I was told it could have something to do with the 'Comfort Control Unit/Computer'. I was also wondering if it might just be low on refrigerant, and be shutting off because of that. Another side note: the system sometimes runs for about 30 seconds after the car has been turned off.

Any ideas? Is there any way to check the coding to see if it might be the CCU or low refridge?
